DESCRIPTION OF SOME EMBODIMENTS

The following embodiments are only examples. Although the specification may refer to “an”, “one”, or “some” embodiment(s) in several locations, this does not necessarily mean that each such reference is to the same embodiment(s), or that the feature only applies to a single embodiment. Single features of different embodiments may also be combined to provide other embodiments.

Embodiments are applicable to any user device, such as a user terminal, as well as to any network element, relay node, server, node, corresponding component, and/or to any communication system or any combination of different communication systems that support required functionalities. The communication system may be a wireless communication system or a communication system utilizing both fixed networks and wireless networks. The protocols used, the specifications of communication systems, apparatuses, such as servers and user terminals, especially in wireless communication, develop rapidly. Such development may require extra changes to an embodiment. Therefore, all words and expressions should be interpreted broadly and they are intended to illustrate, not to restrict, embodiments.

In the following, different exemplifying embodiments will be described using, as an example of an access architecture to which the embodiments may be applied, a radio access architecture based on long term evolution advanced (LTE Advanced, LTE-A), that is based on orthogonal frequency multiplexed access (OFDMA) in a downlink and a single-carrier frequency-division multiple access (SC-FDMA) in an uplink, without restricting the embodiments to such an architecture, however. It is obvious for a person skilled in the art that the embodiments may also be applied to other kinds of communications networks having suitable means by adjusting parameters and procedures appropriately. Some examples of other options for suitable systems are the universal mobile telecommunications system (UMTS) radio access network (UTRAN or E-UTRAN), long term evolution (LTE, the same as E-UTRA), wireless local area network (WLAN or WiFi), worldwide interoperability for microwave access (WiMAX), Bluetooth®, personal communications services (PCS), ZigBee®, wideband code division multiple access (WCDMA), systems using ultra-wideband (UWB) technology, sensor networks, mobile ad-hoc networks (MANETs) and Internet Protocol multimedia subsystems (IMS).

In an orthogonal frequency division multiplexing (OFDM) system, the available spectrum is divided into multiple orthogonal sub-carriers. In OFDM systems, the available bandwidth is divided into narrower sub-carriers and data is transmitted in parallel streams. Each OFDM symbol is a linear combination of signals on each of the subcarriers. Further, each OFDM symbol may be preceded by a cyclic prefix (CP), which is used to decrease Inter-Symbol Interference. Unlike in OFDM, SC-FDMA subcarriers are not independently modulated.

FIG. 1 depicts examples of simplified system architectures only showing some elements and functional entities, all being logical units, whose implementation may differ from what is shown. The connections shown in FIG. 1 are logical connections; the actual physical connections may be different. It is apparent to a person skilled in the art that the system typically comprises also other functions and structures than those shown in FIG. 1.

The embodiments are not, however, restricted to the system given as an example but a person skilled in the art may apply the solution to other communication systems provided with necessary properties.

FIG. 1 shows a part of a radio access network based on E-UTRA, LTE, LTE-Advanced (LTE-A) or LTE/EPC (EPC=evolved packet core, EPC is enhancement of packet switched technology to cope with faster data rates and growth of Internet protocol traffic). E-UTRA is an air interface of Release 8 (UTRA=UMTS terrestrial radio access, UMTS=universal mobile telecommunications system). Some advantages obtainable by LTE (or E-UTRA) are a possibility to use plug and play devices, and Frequency Division Duplex (FDD) and Time Division Duplex (TDD) in the same platform.

FIG. 1 shows user devices 100 and 102 configured to be in a wireless connection on one or more communication channels 104 and 106 in a cell with a (e)NodeB 108 providing the cell. The physical link from a user device to a (e)NodeB is called uplink or reverse link and the physical link from the NodeB to the user device is called downlink or forward link.

The NodeB, or advanced evolved node B (eNodeB, eNB, (“e” stands for evolved) in LTE-Advanced, is a computing device configured to control the radio resources of communication system it is coupled to. The (e)NodeB may also be referred to as a base station, an access point or any other type of interfacing device including a relay station capable of operating in a wireless environment. Typically, a (e)NodeB needs to know channel quality of each user device and/or the preferred precoding matrices (and/or other multiple input-multiple output (MIMO) specific feedback information, such as channel quantization) over the allocated sub-bands to schedule transmissions to user devices. Such required information is usually signalled to the (e)NodeB.

The (e)NodeB includes transceivers, for example. From the transceivers of the (e)NodeB, a connection is provided to an antenna unit that establishes bi-directional radio links to user devices. The antenna unit may comprise a plurality of antennas or antenna elements. The (e)NodeB is further connected to core network 110 (CN). Depending on the system, the counterpart on the CN side can be a serving gateway (S-GW, routing and forwarding user data packets), packet data network gateway (P-GW), for providing connectivity of user devices (UEs) to external packet data networks, or mobile management entity (MME), etc.

A communications system typically comprises more than one (e)NodeB in which case the (e)NodeBs may also be configured to communicate with one another over links, wired or wireless, designed for the purpose. These links may be used for signalling purposes.

The communication system is also able to communicate with other networks, such as a public switched telephone network or the Internet 112. The communication network may also be able to support the usage of cloud services. It should be appreciated that (e)NodeBs or their functionalities may be implemented by using any node, host, server or access point etc. entity suitable for such a usage.

A user device (also called UE, user equipment, user terminal, terminal device, etc.) illustrates one type of an apparatus to which resources on the air interface are allocated and assigned, and thus any feature described herein with a user device may be implemented with a corresponding apparatus, such as a relay node. An example of such a relay node is a layer 3 relay (self-backhauling relay) towards the base station.

The user device typically refers to a portable computing device that includes wireless mobile communication devices operating with or without a subscriber identification module (SIM), including, but not limited to, the following types of devices: a mobile station (mobile phone), smartphone, personal digital assistant (PDA), plug-in data modem (such as a universal serial bus, USB stick), handset, device using a wireless modem (alarm or measurement device, etc.), laptop and/or touch screen computer, tablet, game console, notebook, and multimedia device.

The user device (or in some embodiments a layer 3 relay node) is configured to perform one or more of user equipment functionalities. The user device may also be called a subscriber unit, mobile station, remote terminal, access terminal, user terminal or user equipment (UE) just to mention but a few names or apparatuses.

It should be understood that, in FIG. 1, user devices are depicted to include 2 antennas only for the sake of clarity. The number of reception and/or transmission antennas may naturally vary according to a current implementation.

Further, although the apparatuses have been depicted as single entities, different units, processors and/or memory units (not all shown in FIG. 1) may be implemented.

It is obvious for a person skilled in the art that the depicted system is only an example of a part of a radio access system and in practise, the system may comprise a plurality of (e)NodeBs, the user device may have an access to a plurality of radio cells and the system may comprise also other apparatuses, such as physical layer relay nodes or other network elements, etc. At least one of the NodeBs or eNodeBs may be a Home(e)nodeB. Additionally, in a geographical area of a radio communication system a plurality of different kinds of radio cells as well as a plurality of radio cells may be provided. Radio cells may be macro cells (or umbrella cells) which are large cells, usually having a diameter of up to tens of kilometres, or smaller cells such as micro-, femtoor picocells. The (e)NodeBs of FIG. 1 may provide any kind of these cells. A cellular radio system may be implemented as a multilayer network including several kinds of cells. Typically, in multilayer networks, one node B provides one kind of a cell or cells, and thus a plurality of (e) Node Bs are required to provide such a network structure.

Recently for fulfilling the need for improving the deployment and performance of communication systems, the concept of “plug-and-play” (e)Node Bs has been introduced. Typically, a network which is able to use “plug-and-play” (e)NodeBs, includes, in addition to Home (e)Node Bs (H(e)nodeBs), a home node B gateway, or HNB-GW (not shown in FIG. 1). A HNB Gateway (HNB-GW), which is typically installed within an operator's network may aggregate traffic from a large number of HNBs back to a core network.

Multimedia broadcast multicast services (MBMS) is designed to provide support for broadcast and multicast services by using a point-to-multipoint interface. The MBMS is feasible when a large number of users are interested in same content. It is designed for a plurality of applications, such as mobile TV and radio broadcasting, as well as file delivery and emergency alerts. The MBMS comprises MBMS bearer service and MBMS user service. A multicast standard for Long Term Evolution (LTE) is called evolved multimedia broadcast multicast service (eMBMS). In the eMBMS, network resources are allocated for multicasting by “borrowing” them from available spectrum for the duration of the eMBMS session.

Multimedia broadcast multicast service single frequency network (MBSFN) area typically comprises a group of cells coordinated to achieve an MBSFN transmission (a simulcast transmission that transmits same waveforms simultaneously from multiple cells). This coordinated transmission is usually designed to be seen as a single transmission by a user device.

Multimedia broadcast multicast services (MBMS) are designed to be provided by a multimedia broadcast multicast services gateway (MBMS GW) that conveys IP multicast packets to eNBs that are part of the eMBMS service. It is also responsible for MBMS session control signalling towards E-UTRAN using a mobility management entity (MME) functionality. In the FIG. 1, the multimedia broadcast multicast services gateway (MBMS

GW) is illustrated as a part of the core network 110. The role of an eNB is to join Internet protocol (IP) multicast, terminate a multicast control channel and indicate the beginning and ending of a multicast session to user devices.

In the following, some embodiments are disclosed in further details in relation to FIGS. 2 and 3. Some embodiments are especially suitable for reporting of broadcast-service reception quality in evolved multimedia broadcast multicast service (eMBMS).

When using eMBMS, signal qualities may be estimated and reported to a network (in a similar manner as other radio related measurements are carried out and reported to the network). However, in collecting measurement information on multimedia broadcast multicast service single frequency network (MBSFN) reception quality from user devices located in different parts of an MBSFN area, a possibility exists to receive measurement information indicating poor reception from user devices located at the edge of the coverage of the MBSFN area. Thus it may be difficult to distinguish whether such reports call for adjusting the content source coding or transmission parameters to more robust ones, or whether such problems are limited to the edge of an MBSFN area. If measurement information originates from the edge of an MBSFN area, it is natural that reception quality is degraded. Hence, optimizing code rates, forward error correction coding (FEC coding), selection of a mobile switching center, and consequently bandwidth utilization based on reports from MBSFN-area edges may cause wrong decisions. Thus, it may be feasible to “filter” out these reports to prevent drawing false conclusions and making wrong decisions in network control.

Embodiments in relation to FIG. 2 may be carried out by a user device.

Embodiment starts in block 200.

In block 202, information concerning quality of a multimedia broadcast multicast service single frequency network signal is reported.

Information concerning signal quality may be different measurement results or based on them, such as signal-to-noise ratio (SNR), signal-to-noise and interference ratio (SNIR), received signal power, received signal strength, and Quality-of Service (QoS). It may also be measurement results as averaged or processed in any other suitable manner. Suitable information may vary according to current radio access protocol. In the case of LTE multimedia broadcast multicast service single frequency network (MBMS), some examples of such information are multimedia broadcast-multicast service single-frequency network reference signal received power (MBSFN RSRP), multimedia broadcast-multicast service single-frequency network reference signal received quality (MBSFN RSRQ), and/or multimedia broadcast-multicast service single-frequency network received signal strength indicator (MBSFN RSSI).

In block 204, information on at least one of best neighbour cells is reported.

The at least one of best neighbour cells may comprise the neighbour cell that the user device receives as the strongest on the frequency of the multimedia service area.

In one embodiment, to enable the entity collecting measurements of MBSFN reception quality to distinguish those measurements which are made in the edge of a MBSFN area, a user device may report the identity of its current primary serving cell and/or the neighbour cell that the user device receives as the strongest on the frequency of the MBSFN area. The information on the primary serving cell may be a ell global identity (CGI). The information on a primary serving cell may be in the form of the currently used radio resource control (RRC) information element (RRC IE). The information on the at least one of best neighbour cells may be a physical cell identity (PCI). However, if the reporting is carried out by using the RRC protocol, a node or server is aware of user devices primary serving cell and thus no need for separate reporting exists.

Other identifiers which a user device may also report are the MBSFN-area identity (ID) of the MBSFN area in question, as well as the service-area ID to which the cell broadcasting the MBSFN area belongs.

A user device may acquire a part of system Information of one or more neighbour cells autonomously by interrupting reception of one of its serving cells to be used in determining the identity of the best neighbour cell. Another option may be to restrict measurements and/or signalling to be carried out in user device's RRC_Idle state. Alternatively, in the case a primary cell (PCell) Global Cell identity (ID) is available, a physical cell identity (PCI) from a neighbouring cell may be used by a server to identify which measurement data is related to the edge of an MBSFN area. This information may even be derivable from a regular neighbour cell measurement report a user device conveys to a network, or from a part of it.

Additionally, information on how frequently information concerning quality of the MBSFN signal should be reported may be obtained from a serving network.

The embodiment ends in block 206. The embodiment is repeatable in many ways. One example is shown by arrow 208 in FIG. 2.

Another embodiment which may be carried out by a node, host or server will now be explained by means of FIG. 3. The embodiment starts in block 300.

In block 302, information concerning signal quality is obtained.

Information concerning signal quality may be different measurement results or based on them, such as signal-to-noise ratio (SNR), signal-to-noise and interference ratio (SNIR) and Quality-of Service (QoS). It may also be measurement results as averaged or processed in any other suitable manner. Suitable information may vary according to current radio access protocol. The information may be obtained from a user device. In the case of LTE multimedia broadcast multicast service single frequency network (MBMS), some examples of such information are multimedia broadcast-multicast service single-frequency network reference signal received power (MBSFN RSRP), multimedia broadcast-multicast service single-frequency network reference signal received quality (MBSFN RSRQ), and/or multimedia broadcast-multicast service single-frequency network received signal strength indicator (MBSFN RSSI).

The rate of reporting may differ from the one used for reporting existing mobility measurements in the LTE. Therefore, it may be beneficial to control the rate of reporting separately for MBSFN-related quality measurements. Additionally, this allows limiting network signalling load.

In block 304, information on the location of a cell in relation to a multimedia service area, wherein the information concerning signal quality is created, is obtained.

A multimedia service area may be a multimedia broadcast multicast service single frequency network (MBSFN) area which typically comprises a group of cells coordinated to achieve or receive an MBSFN transmission.

Information on the location of a cell may be information on a primary serving cell and/or on at least one of best neighbour cells. The at least one of best neighbour cells may comprise the neighbour cell that the user device receives as the strongest on the frequency of the multimedia service area. It may be used to distinguish information obtained in the edge of a multimedia service area. The information on the primary serving cell may be a cell global identity (CGI). The information on a primary serving cell may be in the form of the currently used radio resource control information element (RRC IE). Term “best neighbor cell” may mean a neighbour cell that the user device receives as the strongest on the frequency of the MBSFN area.

Other identifiers which a user device may also report are the MBSFN-area identity (ID) of the MBSFN area in question, as well as the service-area ID to which the cell broadcasting the MBSFN area belongs.

Alternatively, in the case a primary cell (PCell) global cell identity (ID) is available, a physical cell identity (PCI) from a neighbouring cell may be used by a server to identify which measurement data is related to the edge of an MBSFN area.

In block 306, utilizing the information concerning signal quality in a network is controlled based on the information on the location of the cell in relation to the multimedia service area.

When a node, such as an eNB, is aware which cell are possible border or edge cells of a multimedia service area, it may append such information to service or signal quality information obtained from a user device before relaying it further, or even refrain from relaying such information. The node may even deny devices on a cell edge area to report service or signal quality.

The embodiment ends in block 308. The embodiment is repeatable in many ways. One example is shown by arrow 310 in FIG. 3.

The steps/points, signaling messages and related functions described above in FIGS. 2 and 3 are in no absolute chronological order, and some of the steps/points may be performed simultaneously or in an order differing from the given one. Other functions may also be executed between the steps/points or within the steps/points and other signaling messages sent between the illustrated messages. Some of the steps/points or part of the steps/points can also be left out or replaced by a corresponding step/point or part of the step/point.

It should be understood that conveying, transmitting and/or receiving may herein mean preparing a data conveyance, transmission and/or reception, preparing a message to be conveyed, transmitted and/or received, or physical transmission and/or reception itself, etc. on a case by case basis. The same principle may be applied to terms transmission and reception as well. Additionally, reporting may herein mean preparing a data conveyance, transmission and/or reception, preparing a message to be conveyed, transmitted and/or received, or physical transmission and/or reception itself, etc. on a case by case basis.
